    All done, how'd everyone find it?

    I felt I did better on the Physiology one than Genetics, probably got an A on both but not an overall A .

    What did you put for the gene probe 4 mark question on the Genetics paper?

    Both of them were OK, but I found the genetics paper easier.

    For the probes question, I wrote about how the DNA strands are split, revealing the bases. The probe is complementary to the mutant allele, so if the mutant allele is present, the probe will join to it by complementary base pairing. When the sample is tested for radioactivity, the test will show radioactivity because the probe had joined to the mutant allele.

    I thought that all in all they were not too bad. Well, they could have been much, much worse anyway! Module 2 was quite good but Module 3 was a little annoying because there were some odd questions (well I thought so anyway). It didn't really fit the 'pattern' of the past papers, there were some questions which I didn't really understand. And I have absolutely no idea how you were meant to get 7 marks out of the last question! Ah well, hopefully I got a couple at least.

    Module 2- great
    Module 3 - ARGH!

    :hmpf:

    I worked out during the exam that if I got every question that I answered right then I'd get 85% ish (on module 3). Module 2 I'm one hell of a lot more confident on, but then I was at GCSE and it turns out I'd messed that one up, so... :s:

    For question 7 you had to describe the mass-flow hypothesis...

    Yep, that's what I got! I was thinking that 666 couldn't be right, but the next question said 'the mouse has heartbeat of 550', so it should be ok.

    Did you get 25 micrometers for the length of the sperm in the genetics paper?

    Lots of wierd questions on mod 3 aswell, cant remember any of them now! Managed to make up lots of answers tho
    I got 666 aswell , wheee ! I think I was too absorbed to notice tho ... !

    Woo, go us.

    Some of the questions were really vague, most of them were only a mark or two though. Like 'suggest how the modified nucleotides stop DNA replication'.
    I think I wrote something about it preventing the sugar-phosphate backbones joining

    ahh , good idea. I think i ended up putting something like, it works the same way as a primer, effectively telling the dna polymerase to 'stop copying here'. hmm dont think thats right tho !!

    Ooooh, this is the only one I got stumped on for unit 2:

    5.d. Something along the lines of 'using your knowledge on genes, how does the relative concentration of growth restriction thingys make roots or stems'... I can't remember the wording of it at all

    I wasn't sure about that one either. Something about providing the right conditions for synthesis of the different genes causing differentiation or promoting the genes?

    Oh yeah, THAT question. I wrote about the hormones telling the cell which genes to express, not sure if I'm right though.

    Oh and also, for the Sanger sequencing question, the base sequence you had to write out was complemetary to the bases in the gel electrophoresis, right?

    I got 666 as well woo .

    Also put the sugar-phosphate backbone idea.

    Module 2 was far harder than module 3 in my opinion. I knew the answers but just couldnt seem to express them at all.

    Ah balls.
